Hi Geoge,

Have you check if the output voltage from the power adapter is good and stable or not. If it is good then the problem can be in the charger power supply circuit. Yes you can turn on the laptop without ram and harddisk except that it does not have any display and in some model the power led will blink indicates there is no connection.

H melusi,

The one verical line could be caused by bad t-con board or the lcd panel have problem. As for the sound problem, have you tested it on a dvd player?

HI Thilanga,
You may need to check the filter cap in the secondary side of smps and make sure no dry joints in the high voltage transformer
